There's this guy who comes once a month to deliver books and gifts for us to buy at work, and I think it's Reader's Digest that he works for. Wosie barks at him ferociously from the moment he steps foot in the door until he leaves. He completely ignores her, like she doesn't even exist, never has tried to pet her, doesn't talk to her, nothing. She knows he doesn't like dogs, and she doesn't like him. I have never seen her act that way with anyone else. Usually she wiggles herself silly until they pet her!
